#XL - T Zoology

In S. cerevisiae, during interphase and early mitosis, Cdc14 is sequestered and inactivated in the nucleolus.

Inactive Tem1-GDP associates with the spindle pole body nearest to the bud as soon as the mitotic spindle forms

#XL - T Zoology

If chromosome segregation occurs properly, extension of the spindle microtubules inserts the daughter SPB into the bud, causing Tem1 to be activated by an unknown mechanism.

#XL - T Zoology

Tem1-GTP activates a protein kinase cascade, which promotes the release of active Cdc14 from the nucleolus and exit from mitosis.

#XL - T Zoology

An inhibitor of the GTPase, called Kin4, localizes to the parent cell but is absent from the bud.

#XL - T Zoology

An inhibitor of Kin4, called Lte1, localizes to the bud but is absent from the parent cell; it inhibits any residual Kin4 that leaks into the bud.
